ELECTRICAL TAP-SOCKET.

SPECIFICATION forming part of Letters Patent No. 699,205, dated May 6, 1902. Application filed August 27, 1901. Serial No. 73,442. lllo model.)

To all whom it may concern:

Be it known that I, EMIL B. MEYROWITZ, a citizen of the United States, residing at the city of New York, in the borough of Manhattau and State of New York, haveinvented certain new and useful Improvements in Electrical Tap-Sockets, of which the following is a full, clear, and exact description.

This invention relates to tap-sockets for electric circuits, and has for its object the production of a simple, cheap, and compact form of electric tap by which the mains of an electric circuit running to the terminals of a lamp or other translating device may be so connected with a second translating mechanism, such as a motor or second lamp, that the two may be electrically joined in either series or multiple circuit, as desired.

It is of course understood that should a small motor, such as is frequently used for operating adental engine or sewing-machine or in medical and laboratory work, be coupled in series with an ordinary incandescent lamp while the full pressure of the current be available on the former its resistance would reduce the efiective candle-power of the latter to a greater or less degree. However, should the requirements of the service in which it is employed call for the development of a smaller amount of power in the motor at a time when the maximum illumination was desired the multiple connection would accomplish this object.

My invention will be described in detail hereinafter with reference to the accompanying drawings, in Which- Figure 1 shows the two main parts of my improved tap-socket in opposite perspective and separated for clearness of illustration. Fig. 2 is a perspective view of the circuit-controlling element. Fig. 3 is a side elevation of the complete socket, and Fig. 4 is a section on line a: an of Fig. 3. Fig. 5 is a perspective view of the plug and cord to be used in connection with the socket. Figs. 6 and 7 are diagrams of the circuits. 7

In its preferred form, as illustrated in the accompanying drawings, my invention comprehends a movable circuit-controllin g device A, composed of the end sections a a, made of hard rubber or other suitable insulating material, the connecting-rods (1 also of insulating material, except at their ends a and (1 which are formed of any desired conducting substance. These ends terminate in the screws a and a which are countersunk when in proper position to the level of the outer faces of the ends a, and are drilled at the center for the admission of the electrodes of the plug P, constituting the terminals of the branch circuit.

B represents a plug forming one of the main mains through the shell I) and central contact, as shown. 0 and 0 represent similar strips secured to the opposed face of the socket O by the screws 0 and connected by the latter with the shell 0 of said socket O. The strips 6 and 0 which face each other without touching, have curved notches at one end, and the strips 1), b and c are perforated at one end for the reception of the ends of the rods a When the parts are assembled, the circuit-closer A has a slight transverse movement, the upturned ends of the strips 1), b 0, and 0 serving as stops for the ends a, and thus fixing the limits of said transverse movement. The screws a and a serve to secure the ends a to the rods a As will be readily understood from the drawings, when the parts B and C are properly assembled and held by a screw projecting from the center of socket G into the boss on piece I) the right end of the strip 0' will he in close proximity to the slotted end of 6 but electric connection will not be established unless
